Gao XY, Li XY, Zhang CY, Bai CY. Scopoletin: a review of its pharmacology, pharmacokinetics, and toxicity. Front Pharmacol 2024; 15:1268464. [PMID: 38464713 PMCID: PMC10923241 DOI: 10.3389/fphar.2024.1268464] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Accepted: 01/24/2024] [Indexed: 03/12/2024] Open
Abstract
Scopoletin is a coumarin synthesized by diverse medicinal and edible plants, which plays a vital role as a therapeutic and chemopreventive agent in the treatment of a variety of diseases. In this review, an overview of the pharmacology, pharmacokinetics, and toxicity of scopoletin is provided. In addition, the prospects and outlook for future studies are appraised. Scopoletin is indicated to have antimicrobial, anticancer, anti-inflammation, anti-angiogenesis, anti-oxidation, antidiabetic, antihypertensive, hepatoprotective, and neuroprotective properties and immunomodulatory effects in both in vitro and in vivo experimental trials. In addition, it is an inhibitor of various enzymes, including choline acetyltransferase, acetylcholinesterase, and monoamine oxidase. Pharmacokinetic studies have demonstrated the low bioavailability, rapid absorption, and extensive metabolism of scopoletin. These properties may be associated with its poor solubility in aqueous media. In addition, toxicity research indicates the non-toxicity of scopoletin to most cell types tested to date, suggesting that scopoletin will neither induce treatment-associated mortality nor abnormal performance with the test dose. Considering its favorable pharmacological activities, scopoletin has the potential to act as a drug candidate in the treatment of cancer, liver disease, diabetes, neurodegenerative disease, and mental disorders. In view of its merits and limitations, scopoletin is a suitable lead compound for the development of new, efficient, and low-toxicity derivatives. Additional studies are needed to explore its molecular mechanisms and targets, verify its toxicity, and promote its oral bioavailability.

Arch Pharm (Weinheim) 2024; 357:e2300438. [PMID: 37984852 DOI: 10.1002/ardp.202300438] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 10/02/2023] [Accepted: 10/24/2023] [Indexed: 11/22/2023]
Abstract
Ifosfamide (IFOS) is a broad-spectrum chemotherapeutic agent that has been extensively used for breast cancer and other solid tumors. Unfortunately, its use is associated with toxicities of several organs. Stenocarpus sinuatus is an Australian tree belonging to the Proteaceae family. In the current study, the phytochemical constituents of S. sinuatus methanol leaf extract (SSLE) were assessed. In addition, the protective effect of SSLE against IFOS-induced nephrotoxicity and hepatotoxicity was evaluated. Rats were randomly divided into six groups: control, IFOS (50 mg/kg), IFOS + SSLE (100 mg/kg), IFOS + SSLE (200 mg/kg), IFOS + SSLE (400 mg/kg), and SSLE (400 mg/kg). Hepatoprotective and nephroprotective potency of SSLE was assessed using different biochemical parameters. The phytochemical investigation resulted in the isolation of four flavonoid glycosides (kaempferol 3-O-β- d-glucopyranosyl-(1→2)-α- l-rhamnopyranoside, kaempferol 3-O-α-rhamnopyranoside, isorhamnetin 3-O-β- d-glucopyranosyl-(1→2)-α- l-rhamnopyranoside, and quercetin 3-O-β- d-glucopyranosyl-(1→2)-α- l-rhamnopyranoside) and a coumarin (scopoletin). This is the first report on the isolated compounds from the genus Stenocarpus. SSLE showed enhancement of kidney and liver functions and reduction of oxidative stress and inflammation. The histopathology of the investigated organs confirmed the protective effect of SSLE. In conclusion, SSLE is considered as a promising candidate that can be used in defense against the toxic effects of IFOS after further clinical trials.

Abstract
BACKGROUND Chukrasia velutina is an enthnomedicinally used plant reported to have significant medicinal values. The present study aimed to explore the pharmacological activities of bark methanol extract using in vitro, in vivo and in silico models. METHODS The study was designed to investigate the pharmacological effects of methanol extract of Chukrasia velutina bark (MECVB) through in vitro, in vivo and in silico assays. Analgesic activity was tested using formalin-induced nociception and acetic acid-induced writhing assays while the antipyretic effect was tested using yeast-induced hyperthermia in mice model. The antioxidant effect was tested using the DPPH and reducing power assay and the cytotoxic screening was tested using the brine shrimp lethality bioassay. In addition, in silico studies were conducted using computer aided methods. RESULTS In the acetic acid-induced writhing assay, the extract showed 28.36% and 56.16% inhibition of writhing for doses of 200 and 400 mg/kg, respectively. Moreover, a dose-dependent formalin-induced licking response was observed in both early and late phase. In yeast-induced pyrexia, the MECVB exhibited (p < 0.05) antipyretic effect. The extract demonstrated an IC50 value of 78.86 μg/ml compared with ascorbic acid (IC50 23.53 μg/ml) in the DPPH scavenging assay. The compounds sitosterol, 5,7-dimethoxycoumarin and scopoletin were seen be effective in molecular docking scores against COX-I (2OYE), COX-II (6COX) and human peroxiredoxin 5 (1HD2). In ADME/T analysis, 5,7-dimethoxycoumarin and scopoletin satisfied Lipinski's rule of five and thus are potential drug candidates. CONCLUSION The bark of Chukrasia velutina showed significant analgesic and antipyretic properties and is a potential source of natural anti-oxidative agents.

Toxicological Safety Evaluation in Acute and 21-Day Studies of Ethanol Extract from Sol anum lyratum Thunb. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:8518324. [PMID: 35399634 PMCID: PMC8991412 DOI: 10.1155/2022/8518324] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 03/11/2022] [Accepted: 03/16/2022] [Indexed: 11/24/2022]
Abstract
Solanum lyratum (Solanaceae) is a traditional Chinese medicine widely used to remedy cold fever, damp-heat jaundice, herpes, and nephritis dropsy. Despite its obvious therapeutic advantages, few toxicological studies have involved the efficacy and safety of its long-term treatment. To investigate the acute and subchronic toxicity of the extract of 75% ethanol extract of whole Solanum lyratum (ESL) after oral administration in mice. In acute toxicity experiment, mice were intragastric administration with ESL at doses of 1000, 2000, 3000, 4000, or 5000 mg/kg for 1 day. In a subchronic toxicity experiment, mice were intragastrically administration with ESL at doses of 180, 360, and 720 mg/kg and 0.9% saline for 21 days. Weight gain, hematological, biochemical, and histopathological analysis of vital organs were evaluated. The presence of aristolochic acid I in ESL was studied using UPLC-QTOF-MS. Phytochemical analysis indicated that the presence of aristolochic acid I in ESL was 0.0025 mg/g. This relatively low concentration is not enough to cause toxicity. In the acute toxicity experiment, neither mortality nor clinical alterations were shown, except for the mild transient diarrhea at 5000 mg/kg. So the LD50 value of ESL was assessed to be more than 5000 mg/kg. In the subchronic toxicity experiment, neither mortality nor treatment-related clinical signs were observed. There was a significant increase in body weight, hemoglobin (HB), and urea nitrogen (BUN) after administration with ESL at 180 mg/kg. In addition, the weight of the stomach was increased and the hematocrit (HCT) was decreased after administration with ESL at 360 mg/kg. The changes were not considered treatment-related toxicological effects because the toxicity and histopathological analysis indicate that the extracts are safe for oral administration.

Abstract
BACKGROUND The number of patients with non-alcoholic fatty liver disease (NAFLD) is rapidly increasing due to the growing epidemic of obesity. Non-alcoholic steatohepatitis (NASH), the inflammatory stage of NAFLD, is characterized by lipid accumulation in hepatocytes, chronic inflammation and hepatocyte cell death. Scopoletin and umbelliferone are coumarin-like molecules and have antioxidant, anti-cancer and anti-inflammatory effects. Cytoprotective effects of these compounds have not been described in hepatocytes and the mechanisms of the beneficial effects of scopoletin and umbelliferone are unknown. AIM To investigate whether scopoletin and/or umbelliferone protect hepatocytes against palmitate-induced cell death. For comparison, we also tested the cytoprotective effect of scopoletin and umbelliferone against bile acid-induced cell death. METHODS Primary rat hepatocytes were exposed to palmitate (1 mmol/L) or the hydrophobic bile acid glycochenodeoxycholic acid (GCDCA; 50 μmol/L). Apoptosis was assessed by caspase-3 activity assay, necrosis by Sytox green assay, mRNA levels by qPCR, protein levels by Western blot and production of reactive oxygen species (ROS) by fluorescence assay. RESULTS Both scopoletin and umbelliferone protected against palmitate and GCDCA-induced cell death. Both palmitate and GCDCA induced the expression of ER stress markers. Scopoletin and umbelliferone decreased palmitate- and GCDCA-induced expression of ER stress markers, phosphorylation of the cell death signaling intermediate JNK as well as ROS production. CONCLUSION Scopoletin and umbelliferone protect against palmitate and bile acid-induced cell death of hepatocytes by inhibition of ER stress and ROS generation and decreasing phosphorylation of JNK. Scopoletin and umbelliferone may hold promise as a therapeutic modality for the treatment of NAFLD.

Abstract
The aggregation of α-synuclein is linked to neurological disorders, and of these, Parkinson's disease (PD) is among the most widely studied. In this background, we have investigated here the effects of three α, β-unsaturated carbonyl based plant metabolites, daidzein, fisetin and scopoletin on α-Syn aggregation. The ThT and light scattering kinetics studies establish that these compounds have ability to inhibit α-Syn fibrillation to different extents; this is confirmed by TEM studies. It is pertinent to note here that daidzein and scopoletin have been predicted to be able to cross the blood brain barrier. ANS binding assays demonstrate that the compounds interfere in the hydrophobic interactions. The tyrosine quenching, molecular docking and MD simulation studies showed that the compounds bind with α-Syn and provide structural rigidity which delays onset of structural transitions, which is confirmed by CD spectroscopy. The results obtained here throw light on the mechanisms underlying inhibition of α-Syn fibrillation by these compounds. Thus, the current work has significant therapeutic implications for identifying plant based potent therapeutic molecules for PD and other synucleinopathies, an area which needs extensive exploration.

Abstract
OBJECTIVES Scopoletin (6-methoxy-7-hydroxycoumarin) is a naturally occurring coumarin belonging to the category of secondary metabolites. Coumarins are commonly found in several herbs and play a prominent role in the defense mechanism of plants. Beneficial effects of scopoletin including antioxidant, anti-diabetic, hepatoprotective, neuroprotective and anti-microbial activity induced via numerous intracellular signalling mechanisms have been widely studied. However, anti-inflammation and anti-tumorigenesis properties of scopoletin are not well documented in the literature. Therefore, the primary focus of the present review was to highlight the plethora of research pertaining to the signalling mechanisms associated with the prevention of the progression of disease condition by scopoletin. KEY FINDINGS Multiple signalling pathways like nuclear erythroid factor-2 (NEF2)-related factor-2 (NRF-2), apoptosis/p53 signalling, nuclear factor-κB (NF-κB) signalling, autophagy signalling, hypoxia signalling, signal transducer and activator of transcription-3 (STAT3) signalling, Wnt-β signalling, Notch signalling are coupled with the anti-inflammation and anti-tumorigenesis potential of scopoletin. SUMMARY Understanding crucial targets in these molecular signalling pathways may support the role of scopoletin as a promising naturally derived bioactive compound for the treatment of several diseases.

Abstract
Silphion was an ancient medicinal gum-resin; most likely obtained from a Ferula species growing in the Cyrene region of Libya ca. 2500 years ago. Due to its therapeutic properties and culinary value, silphion became the main economic commodity of the Cyrene region. It is generally believed that the source of silphion became extinct in the first century AD. However, there are a few references in the literature about the cultivated silphion plant and its existence up to the fifth century. Recently, a rare and endemic Ferula species that produces a pleasant-smelling gum-resin was found in three locations near formerly Greek villages in Anatolia. Morphologic features of this species closely resemble silphion, as it appears in the numismatic figures of antique Cyrenaic coins, and conform to descriptions by ancient authors. Initial chemical and pharmacological investigations of this species have confirmed the medicinal and spice-like quality of its gum-resin supporting a connection with the long-lost silphion. A preliminary conservation study has been initiated at the growth site of this rare endemic Ferula species. The results of this study and their implications on the regional extinction event, and future development of this species will be discussed.

Abstract
Botanicals have a long history of medicinal use for a multitude of ailments, and many modern pharmaceuticals were originally isolated from plants or derived from phytochemicals. Among these, artemisinin, first isolated from Artemisia annua, is the foundation for standard anti-malarial therapies. Plants of the genus Artemisia are among the most common herbal remedies across Asia and Central Europe. The species Artemisia scoparia (SCOPA) is widely used in traditional folk medicine for various liver diseases and inflammatory conditions, as well as for infections, fever, pain, cancer, and diabetes. Modern in vivo and in vitro studies have now investigated SCOPA's effects on these pathologies and its ability to mitigate hepatotoxicity, oxidative stress, obesity, diabetes, and other disease states. This review focuses on the effects of SCOPA that are particularly relevant to metabolic health. Indeed, in recent years, an ethanolic extract of SCOPA has been shown to enhance differentiation of cultured adipocytes and to share some properties of thiazolidinediones (TZDs), a class of insulin-sensitizing agonists of the adipogenic transcription factor PPARγ. In a mouse model of diet-induced obesity, SCOPA diet supplementation lowered fasting insulin and glucose levels, while inducing metabolically favorable changes in adipose tissue and liver. These observations are consistent with many lines of evidence from various tissues and cell types known to contribute to metabolic homeostasis, including immune cells, hepatocytes, and pancreatic beta-cells. Compounds belonging to several classes of phytochemicals have been implicated in these effects, and we provide an overview of these bioactives. The ongoing global epidemics of obesity and metabolic disease clearly require novel therapeutic approaches. While the mechanisms involved in SCOPA's effects on metabolic, anti-inflammatory, and oxidative stress pathways are not fully characterized, current data support further investigation of this plant and its bioactives as potential therapeutic agents in obesity-related metabolic dysfunction and many other conditions.

Effect of scopoletin on phagocytic activity of U937-derived human macrophages: Insights from transcriptomic analysis. Genomics 2020; 112:3518-3524. [PMID: 32243896 DOI: 10.1016/j.ygeno.2020.03.022] [Citation(s) in RCA: 39] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Revised: 03/09/2020] [Accepted: 03/22/2020] [Indexed: 10/24/2022]
Abstract
Scopoletin is a botanical coumarin. Notably, scopoletin effect on phagocytic activity has not been addressed on transcriptomic level. Accordingly, this study investigated the effect of scopoletin on phagocytosis-linked gene transcription. Whole phagocytosis transcriptional profiling of stimulated U937-derived macrophages (SUDMs) in response to scopoletin as compared to non-treated SUDMs was studied. Regarding scopoletin effect on 92 phagocytosis-linked genes, 12 of them were significantly affected (p-value < .05). Seven genes were downregulated (CDC42, FCGR1A/FCGR1C, ITGA9, ITGB3, PLCE1, RHOD & RND3) and five were upregulated (DIRAS3, ITGA1, PIK3CA, PIK3R3 & PLCD1). Moreover, scopoletin enhanced phagocytic activity of SUDMs. The current results highlighted the potential use of scopoletin as immunity booster and as an adjuvant remedy in management of some autoimmune reactions. To the best of our knowledge, this is the first report that unravels the effect of scopoletin on phagocytosis via transcriptomic analysis.

Abstract
Previously non-isolated compounds (scopoletin and β-D-Glucopyranoside, (1R)-O-isopropyl 6-O-(2,3,4-tri-O-acetyl-β-D-xylopyranosyl)-2,3,4-triacetate) were isolated from an organic extract of the Cnidoscolus chayamansa stem. Also, lupeol acetate (main compound, 49.7 mg/g of dry extract) and scopoletin (0.19 mg/g of dry extract) were quantified by HPLC analysis from this organic extract. The protective activity of the C. chayamansa organic extract against hepatotoxicity induced by antitubercular drugs [Rifampicin (50 mg/kg), Isoniazid (50 mg/kg), and Pyrazinamide (100 mg/kg)] are reported. The extract was tested at 200 and 400 mg/kg in Balb/C mice during 85 days, using silymarin (2.5 mg/kg) as positive control. Liver damage was determined using biochemical parameters (AST, ALT, ALP, CHOL, HDL TG, Urea, and CREA), histological analysis, and evaluation of oxidative stress (SOD, CAT, Gpx, Lpx and POx). The extract at both doses favored body weight gain with respect to the anti-TB group; the dose of 200 mg/kg was better. Also, the extract at both doses decreased the values of transaminases (AST, ALT) enzymes (p < 0.05) vs. anti-TB group. In oxidative stress parameters, the SOD value was decreased, as were the levels of peroxidation of lipids and oxidative protein in the group with C. chayamansa extract at 200 and 400 mg/kg vs. the anti-TB group. Histological analyses from liver showed the absence of steatosis in the extract group at 400 mg/kg, and moderate steatosis in the silymarin and extract (at 200 mg/kg) groups with respect to anti-TB group, which demonstrated a steatosis. It should be noted that during the study period, none of the treated mice died. In conclusion, the CHCl3: MeOH extract of C. chayamansa has a hepatoprotective effect against hepatotoxicity induced by anti-TB drugs.

Abstract
In traditional medicine, Morinda citrifolia (Noni) is used to treat various ailments, including skin and respiratory-tract infections. In this work, a bio-directed study (seed extracts) with five bacteria was carried out against four clinical isolates of Methicillin-Resistant Staphylococcus (MRS) and Staphylococcus aureus ATCC 29213 strain to find molecules capable of inhibiting them. Three organic extracts were obtained by maceration of the noni seeds with ascending polarity solvents (n-hexane, dichloromethane and methanol) that were evaluated as antibacterial in the model of bioautography and broth microdilution techniques. The results showed that the methanolic extract was the most active against all bacteria (MIC = 16 mg/mL). The chromatographic fractionation performed on this extract allowed obtaining six fractions (EMF1-EMF6), of which F1, F2 and F5 exhibited activity against some of the bacteria. EMF1 fraction reached an MIC of 25 μg/mL against S. haemolyticus twice as much as the positive control, in which the chemical content is mainly composed of a mixture of γ-butyrolactones (1-2) and esterified fatty acids (3-9); chemical characterization of the nine compounds was carried out based on gas chromatography coupled to masses. EMF2 fraction, presented an MIC of 200 μg/mL against S. aureus 0198 and S. haemolyticus 562B, where a coumarin known as scopoletin (10) was isolated and active against S. aureus 0198 (MIC = 100 μg/mL). EMF5 fraction demonstrated an MIC of 200 μg/mL against S. aureus 0198, S. haemolyticus 562B and S. epidermidis 1042, in which a neolignan known as americanin A (11) was identified, showing activity against S. haemolyticus 562B and S. epidermidis 1042 (MIC = 100 μg/mL). The chemical characterization of isolated compounds 10 and 11 was performed by the analysis of 1H and 13C NMR. Therefore, the methanolic extract, identified and isolated compounds showed important antibacterial activity against the MRS, validating its use in traditional medicine.

Abstract
Thirty phenolic ether derivatives of scopoletin modified at the 7-hydroxy position were synthesized, and their structures were confirmed by IR, ¹H-NMR, 13C-NMR, MS and elemental analysis. Preliminary acaricidal activities of these compounds against female adults of Tetranychus cinnabarinus (Boisduval) were evaluated using the slide-dip method. The results indicated that some of these compounds exhibit more pronounced acaricidal activity than scopoletin, especially compounds 32, 20, 28, 27 and 8 which exhibited about 8.41-, 7.32-, 7.23-, 6.76-, and 6.65-fold higher acaricidal potency. Compound 32 possessed the the most promising acaricidal activity and exhibited about 1.45-fold higher acaricidal potency against T. cinnabarinus than propargite. Statistically significant 2D-QSAR model supports the observed acaricidal activities and reveals that polarizability (HATS5p) was the most important parameter controlling bioactivity. 3D-QSAR (CoMFA: q² = 0.802, r² = 0.993; CoMSIA: q² = 0.735, r² = 0.965) results show that bulky substituents at R₄, R₁, R₂ and R₅ (C₆, C₃, C₄, and C₇) positions, electron positive groups at R₅ (C₇) position, hydrophobic groups at R₁ (C₃) and R₂ (C₄), H-bond donors groups at R₁ (C₃) and R₄ (C₆) will increase their acaricidal activity, which provide a good insight into the molecular features relevant to the acaricidal activity for further designing novel acaricidal agents. Molecular docking demonstrates that these selected derivatives display different bide modes with TcPMCA1 from lead compound and they interact with more key amino acid residues than scopoletin. In silico ADME properties of scopoletin and its phenolic ether derivatives were also analyzed and showed potential to develop as good acaricidal candidates.

Abstract
We recently reported the antineovascularization effect of scopoletin on rat aorta and identified its potential anti-angiogenic activity. Scopoletin could be useful as a systemic chemotherapeutic agent against angiogenesis-dependent malignancies if its antitumorigenic activity is investigated and scientifically proven using a suitable human tumor xenograft model. In the present study, bioassay-guided (anti-angiogenesis) phytochemical investigation was conducted on Nicotiana glauca extract which led to the isolation of scopoletin. Further, anti-angiogenic activity of scopoletin was characterized using ex vivo, in vivo and in silico angiogenesis models. Finally, the antitumorigenic efficacy of scopoletin was studied in human colorectal tumor xenograft model using athymic nude mice. For the first time, an in vivo anticancer activity of scopoletin was reported and characterized using xenograft models. Scopoletin caused significant suppression of sprouting of microvessels in rat aortic explants with IC50 (median inhibitory concentration) 0.06μM. Scopoletin (100 and 200mg/kg) strongly inhibited (59.72 and 89.4%, respectively) vascularization in matrigel plugs implanted in nude mice. In the tumor xenograft model, scopoletin showed remarkable inhibition on tumor growth (34.2 and 94.7% at 100 and 200mg/kg, respectively). Tumor histology revealed drastic reduction of the extent of vascularization. Further, immunostaining of CD31 and NG2 receptors in the histological sections confirmed the antivascular effect of scopoletin in tumor vasculature. In computer modeling, scopoletin showed strong ligand affinity and binding energies toward the following angiogenic factors: protein kinase (ERK1), vascular endothelial growth factor A (VEGF-A), and fibroblast growth factor 2 (FGF-2). These results suggest that the antitumor activity of scopoletin may be due to its strong anti-angiogenic effect, which may be mediated by its effective inhibition of ERK1, VEGF-A, and FGF-2.

Abstract
The objective of this paper was to observe the effects of Solanum lyratum Thunb extract on tumour inhibition, immune function and survival time of tumour-bearing mice. Lung carcinoma-bearing mouse model was established, the tumour-bearing mice were divided into model group, CTX group, Solanum lyratum Thunb extract high-dose group and low-dose group. By the examination of tumour inhibition rate of Solanum lyratum Thunb extract in Lewis lung carcinoma-bearing mice and determination of the number of NK cells and T cell subsets, the survival rate of tumour-bearing mice was observed. Solanum lyratum Thunb extract had some anti-tumour effect in Lewis tumour-bearing mice. The tumour inhibition rate of high-dose group reached 46.28%, and the tumour inhibition rate of low-dose group was 31.42%. Solanum lyratum Thunb extract can improve the NK cell activity of Lewis tumour-bearing mice, increase the number of CD4 cells in the tumour-bearing mice, and significantly increase the survival rate of tumour-bearing mice. The study concluded that Solanum lyratum Thunb extract has some anti-tumour effect and can improve immune function and survival rate of tumour-bearing mice.

Abstract
"Pichi" or "pichi romero" (Fabiana imbricata R. et. P., Solanaceae) is a Chilean plant used as a tea in the Andean regions of Chile and Argentina. A very simple and direct method was developed for the qualitative analysis of polyphenols in the tea by high-performance liquid chromatography (HPLC) with diode array detection and electrospray ionization tandem mass spectrometry. The phenolic constituents identified in the teas were chlorogenic acid (3-O-caffeoylquinic acid), p-hydroxyacetophenone, scopoletin and quercetin derivatives. The glycosides were mainly glucosides from p-hydroxyacetophenone and scopoletin while di- and tri-glycosides from quercetin were the main flavonoids. The content of the main phenolic compounds in the teas (g/100 g lyophilized infusion) was 0.8-1.9 % for scopoletin, 0.4-6.2 % for p-hydroxyacetophenone and 2.1-4.3 % for rutin, respectively. The health-promoting properties reported for this herbal tea can be associated with the presence of several phenolics with known antioxidant, diuretic and antiinflammatory activity.

Abstract
The present study determined the anti-inflammatory activity of scopoletin in gout air pouch model and revealed the underlying mechanisms by in vitro assays. Monosodium urate (MSU) crystal-induced inflammation in mouse air pouch model, an experimental model for acute gout, was used to assess the efficacy of scopoletin. The neutrophil and mononuclear phagocyte numbers and MPO levels were increased significantly six hours after MSU crystal injection into the air pouch, whereas these changes were inhibited substantially upon scopoletin (100 and 200mg/kg, i.p.) treatment. To get insight into the underlying mechanisms, the in vitro studies were performed to investigate the effects of scopoletin on activation of macrophages and resultant production of inflammatory mediators. The secretions of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), prostaglandin E(2) (PGE(2)) and nitric oxide (NO) were elevated in MSU crystal-stimulated RAW 264.7 cells, and scopoletin (30-300 μM) suppressed the production of all mediators. Moreover, RT-PCR assay and western blot analysis indicated that scopoletin regulated the transcriptional level of these mediators via suppression of NF-κB activation and blockade of MAPK signal pathway. Thus, the results clearly indicated that scopoletin inhibited the monosodium urate crystal-induced inflammation both in vivo and in vitro. In combination with our previous findings that scopoletin shows hypouricemic, anti-angiogenesis and pro-apoptotic activities, this compound may be a potential agent for gout therapy and could serve as a structural base for developing new drugs.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Artemisia capillaris and Artemisia iwayomogi, both members of the Compositae family, have been indiscriminately used for various liver disorders as traditional hepatotherapeutic medicines in Korea for many years. AIM OF THE STUDY In this study, the anti-hepatofibrotic effects of Artemisia capillaris and Artemisia iwayomogi were comparatively analyzed using a carbon tetrachloride (CCl(4))-induced liver fibrosis rat model. MATERIALS AND METHODS Hepatic fibrosis was induced via a 10-week course of intraperitoneal CCl(4) injections (50% dissolved in olive oil, 2mL/kg, twice per week). Water extract of Artemisia capillaris (AC) or Artemisia iwayomogi (AI) was orally administered six times per week from the 5th to the 10th week. RESULTS AI (50mg/kg) significantly attenuated the CCl(4)-induced excessive release of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) in serum (p<0.05), and hydroxyproline and malondialdehyde (MDA) contents in liver tissue (p<0.05). Further, AI markedly ameliorated the depletion of total antioxidant capacity (TAC), glutathione (GSH), and superoxide dismutase (SOD) in liver tissue (p<0.01). Unexpectedly, AC did not exert any effects on the above parameters. Histopathological and immunohistochemical analyses revealed that AI drastically reduced inflammation, necrosis, fatty infiltration, collagen accumulation, and activation of hepatic satellite cells in liver tissue. These changes were not observed with AC treatment. Several critical genes of fibrosis-related cytokines including transforming growth factor beta (TGF-β), platelet-derived growth factor beta (PDGF-β), and alpha smooth muscle actin (α-SMA) were more prominently downregulated by AI compared to AC treatment. CONCLUSION Our results show that AI exerts greater hepatoprotective and anti-fibrotic effects as compared with AC via enhancing antioxidant capacity and downregulating fibrogentic cytokines.

Abstract
This paper presents preliminary results on the modification of glassy carbon electrodes with Multiwall Carbon Nanotubes with or without Polyaniline and Pt nanoparticles as electrocatalytic materials for metallic pollutants detection. Electrodes were constructed and incorporated as amperometric detectors of ionic iron electroreduction using the Flow Injection Amperometric technique in aqueous solution. The results not only revealed the modified electrode with nanotubes, polyaniline and platinum nanoparticles were the most selective and sensitive, but also provided an electroanalytic tool to analyze iron in lixiviated samples of polluted soil. The proposed iron sensor exhibited a linear response between 0 and 10 mM with detection and quantification limits of 0.003 and 0.012 μM, respectively. The aqueous samples were taken from a lixiviated solution of polluted soil from Mineral de Pozos, Guanajuato, Mexico, to define the erosion grade of soil.

Abstract
The hepatoprotective potential of Crossostephium chinensis (L.) Makino water extract (CCW) on carbon tetrachloride (CCl(4)) induced liver damage was evaluated in preventive and curative rat models. Not only were indicators of hepatic damage including GPT, GOT, lipid peroxides and TBARS were examined, the activities of antioxidant enzymes (SOD, CAT, GPx) and GSH were examined as well. The results showed that CCW (0.1, 0.5 and 1.0 g/kg) significantly reduced the elevated levels of GPT and GOT by CCl(4) administration (p < 0.05). TBARS level was dramatically reduced, and SOD, CAT, GPx and GSH activities were significantly increased. In addition, CCW decreased NO production and TNF-α activation in CCl(4)-treated rats. Therefore, we speculate that CCW protects against acute liver damage through its radical scavenging ability. CCW inhibited the expression of MMP-9 protein, indicating that MMP-9 played an important role in the development of CCl(4)-induced chronic liver damage in rats. In LC-MS-MS analysis, the chromatograms of CCW with good hepatoprotective activities were established. Scopoletin may be an important bioactive compound in CCW.

Abstract
BACKGROUND Oxidized low-density lipoprotein (oxLDL) is a proatherogenic molecule that accumulates in the vascular wall and contributes to the pathogenesis of vascular dysfunction early in the development of atherosclerosis. The whole plant of Solanum lyratum is a traditional Chinese medicine that has been used for centuries to treat cancer, tumors, and herpes. However, the cellular and molecular mechanisms of its antioxidant effects are still largely unknown. This study tested the hypothesis that Solanum lyratum Thunberg extract (SLE) could block oxLDL-induced endothelial dysfunction in cultured human umbilical vein endothelial cells (HUVECs). Possible mechanisms were explored. METHODS Antioxidative activities of SLE were assayed by measuring the scavenging of 1,1-diphenyl-2-picryl-hydrazyl (DPPH) free radical and the inhibition of copper-mediated or cell-mediated LDL oxidation. Production of reactive oxygen species (ROS) and the expression of adhesion molecules were evaluated in HUVECs after exposure to oxLDL and treatment with SLE. Several apoptotic signaling pathways were investigated. RESULTS SLE scavenged DPPH and also delayed the kinetics of LDL oxidation in a dose-dependent manner. SLE attenuated the level of oxLDL-induced ROS generation, diminished the expression of endothelial NO synthase (eNOS), and enhanced the expression of adhesion molecules (vascular cellular adhesion molecule-1, E-selectin, and monocyte chemotactic protein-1) and the adherence of monocytic THP-1 cells to HUVECs. OxLDL increased the concentration of intracellular calcium, disturbed the balance of the Bcl-2 protein family, destabilized the mitochondrial membrane potential, increased the amount of cytochrome c released into the cytosol, and increased the activation of caspase 3. These detrimental effects were ameliorated dose-dependently by SLE (P < .05). CONCLUSION Crude extracts of Solanum lyratum protect against oxLDL-induced injury in endothelial cells by direct antioxidant action. CLINICAL RELEVANCE Atherosclerosis is a chronic inflammatory disease characterized by lipid-laden lesions within arterialblood vessel walls. Inhibiting the oxidation of low-density lipoprotein may be an effective way to prevent or delay theprogression of atherosclerosis. This study underscores the potential clinical benefits and application of Solanum lyratumextract in controlling oxidized low-density lipoprotein-associated vascular injury and cardiovascular disease.

Abstract
The objectives of this study were to determine the effects of Artemisia capillaris on the viability, antioxidant status, and cytoprotective against oxidative stress induced by hydrogen peroxide in V79 cells. Pretreatment with ethyl acetate fraction increased 363% cell viability compared to the positive control (PC). The ethyl acetate fraction of A. capillaris scavenged intracellular reactive oxygen species (ROS) and increased the activities of cellular antioxidant enzymes like superoxide dismutase (SOD), glutathione peroxidase (GSH-px), and catalase (CAT), and also increased glutathione (GSH) content. It thereby prevented lipid peroxidation which was demonstrated by the inhibition of the formation of thiobarbituric acid reactive substance (TBARS). Furthermore, ethyl acetate fraction reduced the apoptotic cells and cell cycle arrest at G2/M phase induced by H(2)O(2). These findings suggest that A. capillaris ethyl acetate fraction protected V79 cells against H(2)O(2) damage, by enhancing the antioxidative activity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE An ethnobotanical survey was conducted to collect information on the use of medicinal plants by the Hakka living in Guangdong. AIM OF THE STUDY This investigation was to document valuable knowledge represented by Hakka herbal medicine. MATERIALS AND METHODS Information was obtained from semi-structured interviews, personal conversations with practitioners, direct observations, and by reviewing studies of Hakka and Cantonese reported in the literature. RESULTS Our data covered 94 species belonging to 77 genera in 40 families. We found that most species used for medical purposes were for hepatitis (14 species) and skin diseases (12 species). These disorders are prevalent and are primarily treated with medicinal plants. For treatment, the plants were mainly used as teas (Luica, Bugingca and Lopêdca), medicinal baths and soups. The Hakka and non-Hakka people living in Guangdong use different medicinal plants and, in some cases, use the same medicinal plants differently. CONCLUSIONS The fast disappearance of traditional culture and natural resources due to urbanization and industrialization suggests that unrecorded information may be lost forever. Thus, there is an urgent need both to record this valuable Hakka medicinal knowledge and to encourage its transfer to the next generation.

Abstract
Some coumarins possess enhancing effects on lymphocyte mitogen responsiveness. In this investigation, the activity of scopoletin, a coumarin that has been isolated from different plants and in this case specifically from T. cordata Mill., was evaluated. For this purpose, normal T lymphocytes and a hyperproliferative T lymphoma cell line were used. Scopoletin was found to exert a dual action on tumoral lymphocytes exhibiting both a cytostatic and a cytotoxic effect. These effects varied with the concentrations analysed and the time of cell incubation (EC(50): 251+/-15 microg/ml) and were associated to the induction of apoptosis. Scopoletin induced cell proliferation on normal T lymphocytes (Proliferation stimulation index: 1 microg/ml scopoletin: 1.26+/-0.1; 10 microg/ml scopoletin: 3+/-0.25; 100 microg/ml scopoletin: 1.86+/-0.08); this stimulatory action was found to be due to the interaction with kinase C (PKC) protein. These results indicate that scopoletin could be a potential antitumoral compound to be used for cancer treatment.

Abstract
Scopoletin (6-methoxy-7-hydroxycoumarin) is a phenolic coumarin and a member of the phytoalexins. In this study we investigated whether scopoletin caused apoptosis in HL-60 promyelocytic cells and, if so, by what mechanisms. We found that scopoletin induced apoptosis as confirmed by a characteristic ladder pattern of discontinuous DNA fragments in a dose-dependent manner. The signal cascade activated by scopoletin included the heterodimeric redox-sensitive transcription factor NF-kappaB, which exhibited an upregulation of nuclear factor-kappa B (NF-kappaB) translocation to the nucleus by increase of IkappaBalpha degradation. In addition, scopoletin activated caspase-3 as was evidenced by both the proteolytic cleavage of the proenzyme and increased protease activity. Activation of caspase-3 resulted in the cleavage of 116 kDa poly(ADP-ribose) polymerase (PARP) to 85 kDa cleavage product in time-and dose-dependent fashions. Prior treatment of the cells with pyrrolidine dithiocarbamate, a potent inhibitor of NF-kappaB activation, or Ac-DEVD-CHO, a specific caspase-3 inhibitor, prevented scopoletin-induced caspase-3 activation, PARP cleavage, and finally DNA fragmentation. Taken together, these results suggest that scopoletin induces NF-kappaB activation, which, in turn, causes activation of caspase-3, degradation of PARP, and eventually leads to apoptotic cell death in HL-60 cells.

Abstract
An infusion or decoction of the aerial parts of Fabiana imbricata (Solanaceae) is used in traditional medicine in Chile and Argentina as a digestive and diuretic agent. The main sesquiterpene of the plant was identified as 11-hydroxy-4-amorphen-15-oic acid. At doses of 25, 50 and 100 mg/kg, the compound showed a dose-dependent gastroprotective effect in HCl/EtOH-induced gastric lesions in mice reducing the lesions by 68% at 100 mg/kg. Seven derivatives of the terpene were prepared and their gastroprotective effect was assessed in HCl/EtOH-induced gastric lesions in mice. The cytotoxicity of the products was evaluated in fibroblasts and AGS cells. At 100 mg/kg, 11-hydroxy-4-amorphen-15-p-toluidinamide presented the best gastroprotective effect reducing the gastric lesions by 80%, showing a similar effect to lansoprazole at 20 mg/kg. The compound, however, presented higher cytotoxicity than other derivatives with the IC50 ranging between 110 and 145 microm in AGS cells and fibroblasts, respectively. Most compounds proved to be non-toxic showing cytotoxicity values higher than 1000 microm. The spectroscopic data of six 11-hydroxy-4-amorphen-15-oic acid derivatives are presented here for the first time.

Abstract
Activity-guided fractionation of the EtOAc-soluble extract of the whole plants of Sida acuta using a bioassay based on the induction of quinone reductase (QR) in cultured Hepa 1c1c7 mouse hepatoma cells, led to the isolation of ten active compounds of previously known structure, quindolinone (1), cryptolepinone (2), 11-methoxyquindoline (3), N-trans-feruloyltyramine (4), vomifoliol (5), loliolide (6), 4-ketopinoresinol (7), scopoletin (8), evofolin-A (9), and evofolin-B (10), along with five inactive compounds of known structure, ferulic acid, sinapic acid, syringic acid, (+/-)-syringaresinol, and vanillic acid. These isolates were identified by physical and spectral data measurement. A new derivative of quindolinone, 5,10-dimethylquindolin-11-one (1a) was synthesized and characterized spectroscopically. Of the active substances, compounds 1-3 and 1a exhibited the most potent QR activity, with observed CD (concentration required to double induction) values ranging from 0.01 to 0.12 microg/mL. Six compounds were then evaluated in a mouse mammary organ culture assay, with cryptolepinone (2), N-trans-feruloyltyramine (4), and 5,10-dimethylquindolin-11-one (1a) found to exhibit 83.3, 75.0, and 66.7% inhibition of 7,12-dimethylbenz[a]anthracene-induced preneoplastic lesions, respectively, at a dose of 10 microg/mL.

Abstract
The hepatoprotective activity of the aqueous-methanolic extract of Ambrosia maritima was investigated against acetaminophen (paracetamol, 4-hydroxy acetanilide) induced hepatic damage. Acetaminophen at the dose of 640 mg/kg produced liver damage in rats as manifested by the significant (P < 0.001) rise in serum levels of glutamate oxaloacetate transaminase (AST), glutamate pyruvate transaminase (ALT) and alkaline phosphatase (ALP) to 1178.5 +/-118.05; 607.5 +/- 32.6 and 274.16 +/- 8.89 IU/l (n = 10), respectively, compared with respective control values of 97.83+/-3.23; 46.0 +/- 3.92 and 168.67 +/- 7.86 IU/l. Pretreatment of rats with the plant extract (100 and 200 mg/kg) lowered significantly (P < 0.001) the respective serum AST to 203.3+/-5.74 and 157.1 +/- 8.78 IU/l, ALT to 138.67 +/- 7.7 and 87.5 +/- 3.6 IU/l and ALP levels to 238.0 +/- 5.89 and 206.5 +/- 7.5 IU/l, respectively. Treatment of rats with acetaminophen led to a marked increase in lipid peroxidation as measured by malondialdehyde (MDA) (42%). This was associated with a significant reduction of the hepatic antioxidant system e.g. reduced glutathione (GSH) (65%), glutathione reductase (GSH-R) (35%), total glutathione peroxidase (GSH-Px) (32%) and glutathione-S-transferase (GST) (16%). These biochemical alterations resulting from acetaminophen administration were inhibited by pretreatment with A. maritima L. extract. These data suggest that the plant A. maritima L. may act as a hepatoprotective and antioxidant agent.
